Already Ham Radio has the technology, bandwidth, and evreything needed to
implement distribution of over 70 megabytes of Ham Radio data to every
mobile and handheld operator every day. That's a lot of content.
And the frequencies exist, and the sites exist. THink about it. Every
single VOICE repeater is sitting there with an INPUT channel that NOONE is
listenitng to. Therefore, that repeater can stream at 9600 baud this 50
megabytes of ham radio data all day long using existing radios, existing
packet and existing TNC's from that repeater site on its input.
Every second, it drops the stream for 100ms to listen to see if any VOICE
user wants to use the repeater. If no carrier is there, then the stream
continues. If a voice user has keyed up, then the repeater acts normally,
bringing up its voice transmitter for the duration of the voice contact.
When the repeater evntually drops, it goes back to streaming the megabytes
of ham data.
Any ham wanting to collect this content simply puts his 96000 baud radio
listing to that repeaer INPUT to join the net! An AP runs together
building a buffer of that 70 megabytes of ham radio content per day, which
is then instantly accessible at any time with is browser.
Again, we have the sites, the atnennas, the freqs and the radios.
Just a thought.
